Doped fiber amplifiers for you
by Na Huang SEOHave you ever to
think about what fiber amplifiers are? Have you ever think why you can have a
TV show in your home? This should give thanks to the fiber optic manufacturer in china
as they provide us with various fiber amplifiers for use in our daily life.
Today, I just want
to say something about the doped fiber amplifiers. Doped fiber amplifiers
(DFAs) are optical amplifiers that use a doped optical fiber as a gain medium
to amplify an optical signal. They are related to fiber lasers. The signal to
be amplified and a pump laser are multiplexed into the doped fiber, and the
signal is amplified through interaction with the doping ions. With the high
development of high technology and convenient communication, we can buy it from
fiber optic
cable supplier at any time and any place. There is a common example of
this kind of fiber amplifier. The most common example is the Erbium Doped Fiber
Amplifier (EDFA), where the core of a silica fiber is doped with trivalent
erbium ions and can be efficiently pumped with a laser at a wavelength of 980
nm or 1,480 nm, and exhibits gain in the 1,550 nm regions.
Do you figure out
some secrets about doped fiber amplifiers when you go to the market of fiber optic
adaptor wholesale? We can share the information about it together if
you love to.
